improvement in carbureters; and to this end it consists'in a new and improved means for* heating a'nd gasifying the gasolene or otherv hydro-carbon supplied to an internal combustion engine, and in certain'combinations a and features of constructlon, all as hereln- In the accompanying drawings, Figure 1 is a plan of my im roved carbureter and Fig. 2 is a lcent1-al longltudinal section through the same.

In supplying gasolene or other hydro-car-- bon to an internal combustion engine it is desirable 'to add heat to the hydro-carbon to more readily break up the liquid and gasify it and so make a better and more uniform mixture with the air and hence a more pow- -erul and economical explosive mixture.

This has been done before to a certain extent l by running the jacket water from the engine of the mixing c aroundthe carbureter but on account of the large body of gasolene or other hydro-carbon andthe ra idity with which it is used it is usually on y partially heated. In accordance with my invention I provide means whereby the temperature of the hydro-carbon can be heated up to and kept at the temperature of the engine jacket Water andpartially gasiiied before being mixed with air.

As shown in the drawings, 1 is the body of my im roved carburetor. g v

2 is t e float chamber andbetween the float chamber 2.and body 1 is a water space 3. This water s ace occupies a space completely around and eneath t e float chamber 2 and extends through assage 4 under the bottom iiamber 5 and around the s ra nozzle 6 and assage 7 which connects tiie bottom of the oat chamber 2 with the spray nozzle 6.

8 1s the'inlet to admit hot water to the wa'.- terspace 3 and9 isthe outlet from water space 3.`

10 is a float on the stem 11 on the lower end of which is the ball valve 12 in the valve chamber .13.

14 is la plug screwed into and closing the lower end of the valve chamber 13.

15 is a plug screwed into and closing the lower end of the spray nozzle 6.

Plugs 14 and 15 can be taken out to remove any water or other foreign matter deposited from the hydro-carbon.

16 is a cap screwed onto the top ofthe carhureter for closingthe top of the fioat cham- 17 is a boss on the outside of the carbureter body 1 for making a connection to the h drocarbon supply tank (not shown) and olds one end of a pipe '18. Pipe 18 is coiled around the float chamber 2 and in the water space 3, the upper end of which is fastened 'into the boss 17 and the lower end of which is fastened into,the valve chamber 13 and is the means by which the hydro-carbon is conveyed from the outside ofthe carbureter to the' valve chamber 13.

19 is a passage fromv the top of the float chamber.2 to thetop ofthe mixing chamber 5.

20 is a threaded needle valve for opening and closin the assage-19.

21 is a ighrea ed needle valve for opening and closing the passage 22 in the spray nozzle 6..

23 is 'a feather on the needle valve 21 for revolving or being revolved by the gear sector 24.

25 is a gear sector mounted and fastened on the shaft 26 of the throttle 27 and meshorear sector 25- 5'and 31 is aband having ports 32, 32 etc.,

bureter through the up er end of the pipe 18 and flowing down t heated to the temperature of the lWater sur The operation of carbureter is as Hydro-carbon is irst supplied to the carough this pipe is round'- it in the space 3. The hydro. carbon t en fills valve chamber 13 and iiows past the ball valve 12 and rises in the float chamber 2 and spray nozzlev 6 until the iloat 10 is reached a d raised when the ball valve 12 is also raise and the hydro-carbon stop ed from entering the float chamber 2. The 'eight of the hydro-carbon 1n the i'loat chamber is now just belotvl the top of the passage 22 inthe spray nozzle'. The needle valves 20 and 21- are now opened and the engine started, when the suction of the engi e draws air through the ports 30, 30, etc., idro-carbon' from the spray nozzle 6 past t e needle valve 21 and gas from the top of the float chamber 2 past the needle va ve 20, which are mixed in the chamber 5 i and carried to the engine through the passage 29. As soon as thehydro-carbon in Ythe float chamber 2 falls the float 10 descend'sjand carryin with it the stem 11 and valve 12 -more hy ro-carbon is supplied to the Heat chamber 2 keeping a practically constant level of hydro-carbon in the float .chamber 2. The iloW of, mixture from the mixture chamber 5 to the engine is reguchamber 2 or in an lated .by the openingy and closing of the l throttle`27. As the vsuction from the engine increases the air valve 34 automaticallyA opens and supplies the necessary air which is required from the increased iioW of the as from the top of the float chamber 2 and ydro-carbon spray from the spray nozzle 6.

vMy invention. is not limited to the particular construction shown in the drawings as the pipe 18 maybe carried up and down in stral vt lengths in a Water s ace 3 insteado in a circular'path aroun the iioat other suitable manner and Without departing from the spirit of my invention. v f

I claim as myinyention and desire to secure by Letters Patent 1. The combination, in a carbureter of a mixture chamber with a float chamber, a Water jacket around said float chamber and means .in s'aid Water jacket for carrying and heating hydro-carbon before it is delivered into said tloat chamber, substantially as set orth.

2. Inv a carbureter, the combination, of a Water j acketed float chamber, means forheatving hydro-carbonin said `:rater jacket before ing said hydro-carbon'rom said ioat champreserve a constant level of hydro-carbon in said oat chamber, means to regulate the.

nadeel bei' to said mixture chamber in a` heated conJ dition, substantially as set forth.

3. in a device of the character described, the'c'ombination, of a mixin chamber containing a spray nozzle contro led by a needle valve and a mixture passage in Which the iioW of mixture to an engine from said mixture condition, means for delivering said heated hydro-carbon to said mixture chamber and means for carrying the gas generated in said float chamber on account of the -heated hydro-carbon directly from said float chamber to said mixture chamber,` substantially as set forth. f

1. ln a carbureter for internal combustion engines com osed of a Water jacketed lioat chamber and) a mixture chamber, said float chamber having an inlet controlled by means of a loat and valve, a spray nozzle outlet from said iioat chamber to said mixture, chamber and controlled by a valve, a gas outlet from said iioat chamber to said mixture chamber also controlled by a valve, means to admit air to said mixture chamber and means to convey a liquid hydro-carbon through said Water jacket into said float chamber, Where by said hydro-carbon is heated and partially gasiiied, substantially as set forth.

5. In a carbureter for internal cumbustion engines, the combination of'a Water jacketed iioat chamber,ia mixing chamber, means to flow of hydro-carbon from said 'loat cham` ber to said-mixture chamber, means to regulate the iloW of gas from said iioat chamber to said mixture chamber, means to regulate the 105 admission of air to said mixture chamber, means to regulate the flow of mixture of hydro-carbon and air from said mixture chamber to the combustion chamber of an internal combustion engine and' means-to convey said hydro-carbon through said Water jacket whereby the said hydro-carbon is heated and partially Agasiiied, substantiallyas set forth; Y
